[Trends in the incidence of venous thromboembolism in Galicia over a ten year period]

Abstract

Objective: To analyse the trend of serious thromboembolic episodes in Galicia from 2006 to 2015.

Methods: A retrospective observational study was performed using the public network of the Galician Health Service over the 10 year period (2006-2015). It included patients with a primary diagnosis in their discharge report of pulmonary thromboembolism (PTE), stroke, or deep vein thrombosis (DVT).

Data source: Servizo de admisión e documentación clínica, Subdirección de Información e Servizos Tecnolóxicos e Instituto Galego de Estatística. Measurement variables: the number of new cases of thromboembolism occurred in one year, cumulative incidence (number of new cases/ 100,000 persons years), mortality during hospital admission, and annual percentage change (APC).

Results: A total of 50,611 hospital admissions due to a venous thromboembolic event were identified. The highest incidence was found for stroke in men aged 80 years or older, with 940.84 new cases per 100,000 population per year. All thromboembolic events were more common in men, with the exception of PTE in young and older women. A continued increased was identified in all the thromboembolic events with an APC of 2.20%. The temporal evolution of the cumulative incidence for PTE was split into two segments, with an annual increase of 10.65% from 2006 to 2011, and a smaller increase since 2011. The cumulative incidence trend showed an APC for stroke of 1.56%.

Conclusion: This study reveals an increase in the evolutionary trend of hospital admissions for PTE and stroke during the period 2006-2015 in Galicia.
